DESCRIPTION
"The gmplsTunnelTable sparsely extends the mplsTunnelTable of
MPLS-TE-STD-MIB. It allows GMPLS tunnels to be created between
an LSR and a remote endpoint, and existing tunnels to be
reconfigured or removed.
Note that only point-to-point tunnel segments are supported,
although multipoint-to-point and point-to-multipoint
connections are supported by an LSR acting as a cross-connect.
Each tunnel can thus have one out-segment originating at this
LSR and/or one in-segment terminating at this LSR.
The row status of an entry in this table is controlled by the
mplsTunnelRowStatus in the corresponding entry in the
mplsTunnelTable. When the corresponding mplsTunnelRowStatus has
value active(1), a row in this table may not be created or
modified.
The exception to this rule is the
gmplsTunnelAdminStatusInformation object, which can be modified
while the tunnel is active."

protection scheme, such as 1:N protection, should be used to

DESCRIPTION
"This value instructs the source node on how to perform path
computation on the explicit route specified by the associated

dynamicFull
The user specifies at least the source and
destination of the path and expects that the Constrained
Shortest Path First (CSPF) will calculate the remainder
of the path.
explicit
The user specifies the entire path for the tunnel to
take. This path may contain strict or loose hops.
Evaluation of the explicit route will be performed
hop by hop through the network.
dynamicPartial
The user specifies at least the source and
destination of the path and expects that the CSPF
will calculate the remainder of the path. The path
computed by CSPF is allowed to be only partially
computed allowing the remainder of the path to be
filled in across the network.
When an entry is present in the gmplsTunnelTable for a
tunnel, gmplsTunnelPathComp MUST be used and any
corresponding mplsTunnelHopEntryPathComp object in the
mplsTunnelHopTable MUST be ignored and SHOULD not be set.
mplsTunnelHopTable and mplsTunnelHopEntryPathComp are part of

DESCRIPTION
"The gmplsTunnelCHopTable sparsely extends the
mplsTunnelCHopTable of MPLS-TE-STD-MIB. It is used to indicate
additional information about the hops of a GMPLS tunnel defined
in the mplsTunnelTable and gmplsTunnelTable, as computed by a
constraint-based routing protocol, based on the
mplsTunnelHopTable and the gmplsTunnelHopTable.
Each row in this table is indexed by the same indexes as in the
mplsTunnelCHopTable. It is acceptable for some rows in the
mplsTunnelCHopTable to have corresponding entries in this table
and some to have no corresponding entry in this table.
Please note that since the information necessary to build
entries within this table may not be supported by some LSRs,
implementation of this table is optional.
Furthermore, since the information in this table is actually
provided by a path computation component after the path has been
computed, the entries in this table are provided only for
observation, and hence, all objects in this table are accessible
exclusively as read-only."

cause of an error and identifies an error that has been received
